Alfa Laval spiral heat exchangers are designed to handle the toughest heat transfer challenges. Whether its frequent fouling from dirty media, or limitations from pressure drop and floor space, they are the ultimate problem solver for liquid-to-liquid and two-phase duties.
Jul 18, 2004 · Jul 18, 2004 · Helical Coil Heat Exchangers. These heat exchangers, including a sister type called a spiral heat exchanger, refer to a helical tube configuration that are coiled to form the two channels in a counter-flow arrangement. Each channel has one long curved path. Design and experimental analysis of a helical coil phase Dec 15, 2018 · Dec 15, 2018 · Fig. 1, Fig. 2b show the key components and assembly dimensions of the PCM heat exchanger. The final design has the following dimensions:29.53 cm (1 ft) in length and 16.64 cm (6.55 in. in outer diameter. The top and bottom ends of the container were attached to two square grooved acrylic plates having a thickness of 0.9525 cm (3/8 in. and 19.05 cm (7.5 in. in length (Fig. 1a).
The coiled tube bundle is fit into a two-piece casing. When the casing is tightened, it is designed to slightly compress the tubes. Because of the tight fit, the shellside fluid is forced to circulate in a spiral pattern created by the open spaces between the coils. Advantages of Graham Heliflow Spiral Tube Heat Exchangers. Higher efficiency Helically Coiled Heat Exchangers Offer AdvantagesSimilarly, helical coil units are used as seal coolers for liquid vacu-um pumps by removing the heat absorbed by the liquid ring a result of heat generated by the pump itself and the heat released by condensing vapors during their compression. Condensers. Helical coil heat exchangers
Apr 01, 2018 · Spiral-wound heat exchangers (SWHEs) is a special compact shell and tube heat exchangers, whose unit volume has a large heat transfer area, about 100170m2. SPECIALTY HEAT EXCHANGERS 101 - ASELCOSpiral tube or coil Spiral tube or coil Offering high efficiency in a small footprint for high pressure applications, this type of heat exchanger consists of a multi-tube spiral assembly inserted into a shell, where two paths are created for counterflow heat transfer that is more efficient than a typical shell and tube heat exchanger.
Spiral Tube SENTRY SPIRAL TUBE A spiral tube heat exchanger is a spirally coiled tube and manifold assembly fitted into a compact shell that optimizes heat transfer efficiency and space. The spiral shape of the coil and shell flow paths creates centrifugal force that enhances heat transfer on both sides in a true counterflow arrangement. US4893672A - Counter-flow heat exchanger with helical tube A counter-flow heat exchanger includes helical tube bundles for passage of a primary fluid, the helical tube bundles forming a closed helical flow channel between a core tube and a tubular shell
Mar 29, 2019 · Mar 29, 2019 · Alfa Laval is the only supplier on the market with more than a half-century of experience with spiral technology. Today our spiral heat exchangers can be found in plants around the world, solving tough problems in
